problem catching signals with scene runner

[h-lober]

Man, I'm at a loss here. Following the documentation I tried to catch a signal of a scene with a scene runner but i can't make it work.

the signal definition in the class of ob is just
signal transform_changed

here are the variations I tried:

func test_input_on_handles_emits_transform_changed() -> void:
	assert_signal(ob).is_signal_exists("transform_changed")
	sr = scene_runner(ob)
	ob.transform_changed.emit()
	await sr.await_signal("transform_changed", [ob], 100)
	ob.transform_changed.emit()

func test_input_on_handles_emits_transform_changed() -> void:
	assert_signal(ob).is_signal_exists("transform_changed")
	sr = scene_runner(ob)
	sr.invoke("emit_signal", "transform_changed")
	await sr.await_signal("transform_changed", [ob], 100)
	sr.invoke("emit_signal", "transform_changed")

func test_input_on_handles_emits_transform_changed() -> void:
	assert_signal(ob).is_signal_exists("transform_changed")
	sr = scene_runner(ob)
	ob.transform_changed.emit()
	await sr.await_signal_on(ob, "transform_changed", [], 100)
	ob.transform_changed.emit()

func test_input_on_handles_emits_transform_changed() -> void:
	assert_signal(ob).is_signal_exists("transform_changed")
	sr = scene_runner(ob)
	sr.invoke("emit_signal", "transform_changed")
	await sr.await_signal_on(ob, "transform_changed", [], 100)
	sr.invoke("emit_signal", "transform_changed")

also later the signal will emit a "Transform2D" and i would like to know if it just emitted the signal regardless of the exact parameter
would I ask for
await sr.await_signal_on(ob, "transform_changed", [any()], 100)
or something else?

GDUnit4 has been a blast to use but everything to do with asserting signals is very frustrating to me atm

Can anyone give me some guidance on this please?

At first, have you read the documentation ?
With assert_signal you will catch only signals starting on the next engine main thread cycle.

For example, if you emit a signal in “_ready()”, it is immediately sent on “add_child()” call. Do expecting to catch the signal using await_signal is wrong, because you can't await a signal that already is emitted.
If you want to catch all signals since a specific time stamp you need to use the monitor_signals

       # start to watch on the emitter to collect all emitted signals
	var emitter_a := monitor_signals(MyEmitter.new())

       # emit signal `my_signal_a` on emitter_a
	emitter_a.do_emit_a()
	await assert_signal(emitter_a).is_emitted('my_signal_a')

Here is an example to wait for signal test_signal_counted with any int value

	# wait until signal 'test_signal_counted' is emitted by using any_int() matcher for signal arguments
	await assert_signal(signal_emitter).is_emitted("test_signal_counted", [any_int()])

	# should also work with any() matcher
	signal_emitter.reset_trigger()
	await assert_signal(signal_emitter).is_emitted("test_signal_counted", [any()])
